Market Trends

10

● California growing slowly ● High cost – specifications, measurement , interconnection ● Projects driven by State grants

● California digester focused ● Landfill limited due to N2 removal requirement

● Interest in small scale continues (<200 SCFM) ● Only recently has cost dropped to economical point

● Municipal WWTP digester activity increasing ● Commercial and technical requirements hamper growth ● Much higher cost and longer timeline than private development

● Growing number of technology suppliers ● RINS attractive but ongoing long term concern ● International activity continues high. Highly competitive. ● Biogas to hydrogen interest growing
